DUMP CAR.

Application le'd December 28, 1923. Serial No. 683,114.

To all whom, t may concern.'

Be it known that I, HOWARD MARTIN, a citizen of the United States, and aresident ot the city of Monmouth, in the county of `Warren and State of Illinois, have invented certain new and useful improvements in a Dump Gar; and l hereby declare that the following is afull, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this speciiication.

rlhis invention relates to dump cars of that type involving a downwardly swinging bottom door and it is among the objects of this invention to provide control and sustaining mechanism for the door that is durable in use, simple in operation, cheap in construction and maintenance and in which parts may be readily replaced. l

The invention comprises the novel structure and combinations herein described and more particularly pointed out and delined in ln the accompanying drawings which il lustrate a preferred embodiment of this invention and in which similar reference numerals refer to similar features in the different views:

Figure l is a side elevational view of a dump car embodying this invention.

Figure 2 is a top plan view of the same with parts broken away.

Figure 3 is an enlarged fragmentary elevational view of the dump car illustrating the operation of the same.

Figure 4 is a sectional View upon the line 4 4: of Figure 3.

Figure 5 is an enlarged sectional view upon the line 5-5 of Figure 3.

As shown on the drawings:

In referring to the drawings which illustrate one embodiment of this invention, there is shown a dump car provided with swing sections or doors l in the bottom. Any number of doors may be provided in connection with each car, and as they are all similar only one will be described. Along the central part of the under side of the bottom of the car there extends a center sill or beam or abutment 2 which may consist of channel sections as shown in Figure 4C or any other suitable construction. A pair ot U shaped hinge members 3 are rigidly secured to the beam 2 adjacent the bottom door-way. The doors 1 are provided with supporting cleats i uponthe bottom thereof. These cleats are so spaced and ot' such dimensions as to it within the hinge member 3 to which they are pivoted by bolts 5 (Figure 2). They are likewise firmly secured to the bottom of the doors and extend beyond the front end thereof as clearly shown in Figures 4; and 5. A pair of parallel links 6 are vpivoted at their lower ends by a pivot pin 14 to the projecting end of each cleat 4. The upper ends of these links are pivoted to a lever .7 by a bolt 9 intermediate the ends of said lever. The lower end of each lever is pivoted by means oit a bolt l5 in a biurcated support 8 attached to the side of the car, and the axis of such pivot is spaced suiiiciently from the side of the car so that when the lever 7 lies against the car it is beyond dead center and any downward pull by the link 6 tends to firmly bind the lever 7 against the side of the car. For this purpose the lower part or" each lever, below the pivot 8 that connects theflinks 6 is outwardly inclined as clearly shown in Figure 5, so that the upper part of the lever may lie fiat against the side of the car.

.Y For holding these levers in their operative position, a latch 10 is pivoted by means of a bolt 16 or the like adjacent the upper end of each lever and is adapted to be swung over the lever, and behind a suitable keeper ll. Y

In the present instance, l' have shown a pair oi' levers attached to each door. It should however be understood that any number ot such levers may be applied to a door, according to the teachings of this invention.

The operation of dumping resulting from 'this invention is as follows:

Assuming that a is loaded with coal or the like, the levers 7 will be latched to the car as shown in Figure l. To empty the car, the latches 10 are swung up into inoperative position. The levers 7 are then pulled outwardly by prying with a stick and as soon as the pivots 9 pass beyond dead center, the load on the doors l will become effective and swing the latter downwardly upon their pivots until they are held by the links (i and levers 7 as shown Yliiade, and numerous details of construction may be varied through a wide range with- V out departing from the principles of this invention, and I therefore do not purpose limiting thepatent granted hereon, other- 'wise than necessitated by the prior art.

I elairn as my invention:

In a dumpr ear, a hinged bottom sect-ion,. oleats'extending beyond said section, links .pivoted tothe ends of said cleats, vlevers, pivoted vto the ysides of the car and pia-fote'd intermediate. their ends to said links., and lat-ches for engaging over said levers when the same are in operative positionfthe lower ends of said levers being outwardly inclined whereby the pivotal connections thereofY with said links normally lie beyond dead center.

2. ln a dump car, a hinged bottom sectiony a pair of links connected to said section` a lever pivoted 'to the side of said car and connected intermediate its ends to said links, a latch for normally holding said lever against 'the side of -the car, the' `oonstruction being such that the pull of said links upon the lever will normally tend to bind the same against the car.

3. In ja dump car, a hinged bottom scction, means connected to said section and adapted for embracing the exterior side of the car, and a lever pivoted at its lower end to the exterior side of the ear and connected intermediate its ends to said means and means for normally confining said lever against said car.

In testimony whereof I have hereunto subscribed my nam-e in the presence of two subscribing witnesses. V Y
